1. Semester Review

2. The Tailored Design Method

3. Uses multiple motivational features in compatible and mutually supportive ways to encourage high quantity and quality of responses

4. The Tailored Design Method Premised on social exchange perspective on human behavior Assumes that the likelihood of responding is greater when the expected rewards outweigh the anticipated costs

5. The Tailored Design Method Gives attention to all aspects of contacting and communicating with respondents Encourages response by considering survey sponsorship, the nature of the population and variations within it, and content of questions

6. The Tailored Design Method Emphasizes reducing errors of coverage, sampling, nonresponse, and measurement

7. Coverage Error Occurs when all members of a population do not have a known, non-zero probability of selection Occurs when those who are excluded are different from those who are included

8. Sampling Error Results from surveying only some rather than all members of a population Represented by B, the bound on the error of estimation

9. Nonresponse Error Occurs when people selected do not respond and are different than those who do Nonresponse can occur at the level of items within a survey or at the level of the survey – MAR – MCAR

10. Measurement Error Occurs when responses are inaccurate or imprecise Primarily related to poor layout and poor design and wording of questions

11. Social Exchange and Surveys Addresses three central questions about design and implementation 1.How can the perceived rewards for responding be increased? 2.How can the perceived costs of responding be reduced? 3.How can trust be established so that people believe the rewards will outweigh the costs of responding?

12. Increasing Benefits Provide information about the survey Ask for help or advise Show positive regard Say thank you Support group values Give tangible rewards Make the questionnaire interesting Provide social validation Inform people that opportunities to respond are limited

13. Decreasing Costs Make it convenient to respond Avoid subordinating language Make the questionnaire short and easy to complete Minimize requests for personal or sensitive information Emphasize similarity to other requests or tasks to which a person has already responded

14. Establishing Trust Obtain sponsorship by legitimate authority Provide a token of appreciation in advance Make the task appear important Ensure confidentiality and security of information

15. Features that can be Tailored Survey mode – Singular or multiple Sample design – Type of sample – Number of units sampled Incentives – Type of incentive – Amount or cost of incentive – Before or after

16. Features that can be Tailored Contacts – Number of contacts – Timing of initial and subsequent contacts – Mode of each contact – Whether contacts will be personalized – Sponsorship information – Visual design of each contact – Text or words in each contact

17. Features that can be Tailored Additional materials – Whether to provide them at all – Type of materials (e.g., research report) – Visual design of materials – Text or wording of materials

18. Features that can be Tailored Questionnaire – Topics included – Length (duration, number of pages/screens, number of questions) – First page or screen – Visual design – Organization and order of questions – Navigation through questionnaire

19. Features that can be Tailored Individual questions – Topic (sensitive, of interest to the respondent) – Type (open-ended versus closed-ended) – Organization of information – Text or wording – Visual design

20. Coverage and Sampling

21. Central Terminology An element is an object on which a measurement is taken A population is a collection of elements to which an inference is made from a sample A sample is a collection of sampling units drawn from a frame or frames Sampling units are nonoverlapping collections of elements from the population that cover the entire population A frame is a list of sampling units

22. Central Terminology A completed sample is the units that respond Sampling error is the result of collecting data from only a subset, rather than all, units from a frame – Again, represented by B, the bound on the error of estimation

23. Coverage The degree to which the units in a sampling frame correspond to the population of interest Coverage is likely one of the most serious problems in most surveys

24. Coverage and Frame Problems

25. Reducing Coverage Error Central questions: – Does the list contain everyone in the survey population? – Does the list include people who are not in the study population? – How is the list maintained and updated? – Are the same sample units included on the list more than once? – Does the list contain other information that can be used to improve the survey?

26. An Overview of Crafting Good Questions

27. Issues to Consider 1.What survey mode(s) will be used to ask the questions? 2.Is the question being repeated from another survey, and/or will answers be compared to previously collected data? 3.Will respondents be willing and motivated to answer accurately? 4.What type of information is the question asking for?

28. Choosing Words and Forming Question 1.Make sure the question applies to the respondent 2.Make sure the question is technically accurate 3.Ask one question at a time 4.Use simple and familiar words 5.Use specific and concrete words to specify the concepts clearly 6.Use as few words as possible to pose the question 7.Use complete sentences with simple sentence structures 8.Make sure “yes” means yes and “no” means no 9.Be sure the question specifies the response task

29. Visual Presentation of Survey Questions 1.Use darker and/or larger print for the question and lighter and/or smaller print for answer choices and answer spaces 2.Use spacing to create subgrouping within a question 3.Visually standardize all answer spaces or response options 4.Use visual design properties to emphasize elements that are important to the respondent and to deemphasize those that are not 5.Make sure words and visual elements that make up the question send consistent messages 6.Integrate special instructions into the question where they will be used rather than including them as freestanding entities 7.Separate optional or occasionally needed instructions from the question stem by font or symbol variation 8.Organize each question in a way that minimizes the need to reread portions in order to comprehend the response task 9.Choose line spacing, font, and text size to ensure the legibility of the text

30. From Questions to a Questionnaire

31. General Premises The design of a questionnaire should consider how to motivate the recipient to respond It should also avoid measurement errors, ranging from order effects to item nonresponse

32. Guidelines for Ordering Questions

33. Ordering Questions General guidelines 1.Group related questions that cover similar topics, and begin with questions likely to be salient to nearly all respondents 2.Choose the first question carefully 3.Place sensitive or potentially objectionable questions near the end 4.Ask questions about events in the order that they occurred 5.Avoid unintended order effects

35. Guidelines for Creating a Common Visual Stimulus

36. Visual Stimulus General guidelines 1.Establish consistency in the visual presentation of questions (across pages and screens) and use alignment and vertical spacing to help respondents organize information on the page 2.Use color and contrast to help respondents recognize the components of the questions and the navigational path through the survey 3.Visually group related information in regions through the use of contrast and enclosure 4.Use visual elements and properties consistently across questions to emphasize or deemphasize certain types of information 5.Avoid visual clutter 6.Minimize the use of matrixes and their complexity

39. Guidelines for Mail Questionnaires

40. Mail Questionnaires General guidelines 1.Determine whether keypunching or optical imaging and scanning will be used, and assess the limitations imposed on designing and processing questionnaires 2.Construct paper questionnaires in booklet formats, and choose physical dimensions based upon printing and mailing considerations 3.Decide question layout and how questions will be arranged on each page 4.Use symbols, contrast, size, proximity, and pagination effectively when designing branching instructions to help respondents correctly execute them 5.Create interesting and informative front and back pages that will have wide appeal to respondents 6.Avoid placing questions side-by-side on a page so that respondents are asked to answer two questions at once

45. Guidelines for Web Questionnaires

46. Web Questionnaires General guidelines 1.Decide whether an electronic alternative is appropriate 2.Choose how the survey will be programmed and hosted, commensurate with needs, skills, and sponsorship 3.Take steps to ensure that questions display similarity across platforms, browsers, and user settings 4.Decide how many questions will be presented on each page and how questions will be presented 5.Develop a screen format that emphasizes the respondent rather than the sponsor

47. Web Questionnaires General guidelines 6.Use a consistent page layout across screens and visually emphasize questions information that respondents will need to complete the survey while deemphasizing information not essential to the task 7.Do not require responses unless absolutely necessary 8.Design survey-specific and item-specific error messages to help respondents troubleshoot 9.Evaluate carefully the use of interactive features, balancing improvements in measurement with the impact on respondent burden and the implications with mixed-mode surveys

48. Web Questionnaires General guidelines 10.Use audiovisual capabilities sparingly, and evaluate the differential effect they have on respondents 11.Allow respondents to stop the survey and finish completing it at another time 12.Whenever possible, collect paradata that provide feedback on how respondents interact with questionnaire 13.Test the survey using a variety of platforms, connection speeds, browsers, and user-controlled settings, and test the database to ensure that items are collected and coded accurately 14.Take screenshots of each page of the final questionnaire for testing and documentation

51. Guidelines for Pretesting Questionnaires

52. Pretesting Questionnaires General guidelines 1.Obtain feedback on the draft of the questionnaire from a number of people, each of whom has specialized of some aspect of questionnaire quality 2.Conduct cognitive interviews of the complete questionnaire in order to identify wording, question order, visual design, and navigational problems 3.When the stakes are high, consider experimental evaluations of questionnaire components 4.Conduct a small pilot study with a subsample of the population in order to evaluate interconnections among questions, the questionnaire, and implementation procedures

53. Implementation Procedures

54. Mail Survey Implementation

55. When high quality implementation procedures are used, response rates of 50%-70% are not uncommon – In my own work, I have had response rates as high as 90% Implementation must receive considerable thought and planning – It should not occur after questionnaire design, but simultaneously

56. Mail Survey Implementation General guidelines 1.To the extent possible, personalize all contacts to respondents (even when names are unavailable) 2.Send a token of appreciation with the survey request 3.Use multiple contacts, each with a different look and appeal 4.Carefully and strategically time all contacts 5.Select all mail-out dates with the characteristics of the population in mind

57. Mail Survey Implementation General guidelines 6.Place information in the mailing exactly where it needs to be used 7.Take steps to ensure that mailings will not be mistaken for junk mail or marketing materials 8.Evaluate the size and weight of mailing materials on mailing costs 9.Assemble the mailings in a way that maximizes the appealing aspects of each element when the package is opened

58. Mail Survey Implementation General guidelines 10.Ensure that all addresses in the sample comply with current postal regulations 11.Assign an individual ID number to each sample member 12.Establish procedures for dealing with undeliverable mail 13.Establish procedures for dealing with returned incentives 14.Establish procedures for dealing with respondent inquiries 15.Evaluate early returns for problems that can be addressed mid-stride

59. Prenotice Letter Sent to respondents a few days prior to the questionnaire It notes that a questionnaire is for an important survey that will arrive in a few days and that the person’s response will be greatly appreciated This letter can increase response rates by 3%-6% – No recent research comparing postcards to letters (I prefer the former)

61. Questionnaire Mailing Includes a detailed cover letter explaining why a response is important The questionnaire A prepaid postage envelope A token incentive if one is to be provided

63. Thank You Postcard Sent a few days to a week after the questionnaire The mailing expresses appreciation for responding and indicates that if the completed questionnaire has not yet been mailed it is hoped that it will be returned soon

65. Replacement Questionnaire Sent to respondents 2 to 4 weeks after the previous questionnaire mailing It indicates that the person’s completed questionnaire has not yet been received and urges the recipient to respond

67. Final Contact Sent using a different mode of delivery 2 to 4 weeks after the previous mailing The different mode of contact distinguishes each type of final contact from regular mail delivery Special contacts have been shown to increase response

68. Web Survey Implementation

69. Major concerns associated with web surveys – Mode of initial contact – Extent to which personalized elements can be used – Whether and how incentives are delivered – Timing of contacts

70. Web Survey Implementation General guidelines 1.To the extent possible, personalize all contacts to respondents 2.Send a token of appreciation with the survey request 3.Use multiple contacts and vary the message across them 4.Carefully and strategically time all contacts with the population in mind 5.Consider contacting respondents by another mode when possible

71. Web Survey Implementation General guidelines 6.Keep e-mail contacts short and to the point 7.Take steps to ensure that e-mails are not flagged as spam 8.Carefully select the sender name and address the subject line text for e-mail communications 9.Provide clear instructions for how to access the survey 10.Make obvious connections between the opening screen and other implementation features

72. Web Survey Implementation General guidelines 11.Assign each sample member a unique ID number 12.Know and respect the capabilities and limits of the web server(s) 13.Establish a procedure for dealing with bounced e-mails 14.Establish procedures for dealing with returned incentives 15.Establish procedures for dealing with respondent inquiries 16.Implement a system for monitoring progress and evaluating early completes

73. When More than one Survey Mode is Needed

74. Why Consider a Mixed-Mode Survey Design Lower costs Improve timeliness Reduce coverage error Deliver incentives

75. Four Types of Mixed-Mode Surveys

76. Type I Use one mode to contact respondents and to encourage response by a different mode

77. Type II Use a second mode to collect responses from the same respondents for specific questions within a questionnaire

78. Type III Use alternative modes for different respondents in the same survey period

79. Type IV Use a different mode to survey the same respondents in a later data collection period

80. Mixed-Mode Surveys and their Implications TypeMotivationLimitations I.Use one mode to contact respondents and to encourage response by a different mode Improve response rates Reduce coverage and nonresponse error Increased implementation costs II.Use a second mode to collect responses from the same respondents for specific questions within a questionnaire Reduce measurement error Reduce social desirability bias for sensitive question Increased design costs Increased nonresponse if respondent must respond by other mode at a later time III.Use alternative modes for different respondents in a the same survey period Improve response rates Reduce coverage and nonresponse error Reduce survey costs Increased design costs Measurement error from differences that may be confounded with differences among subgroups IV.Use a different mode to survey the same respondents in a latter data collection period Different modes become available to survey respondents Reduce survey costs Increased design costs Measurement error from mode differences that impact the ability to measure change over time

81. Why Different Survey Modes Sometimes Produce Different Answers to Survey Questions

82. Presence versus Absence of an Interviewer Locus of control Normative question order effects Social desirability Acquiescence

83. Aural versus Visual Communication Effects Primacy/recency effects
